Each end of this doubletree is emward inner bends 12 of the levers 10 serve 5o braced by a tubular or sleeve-like clip 4, the to bring the lines of draft ot the outer and Ioo inner singletrees in proper relation to the structure being operated upon. To the outer end ot each lever l0 is attached, preferably by a pivot 16, a link 15, in the outer end of which is formed au eye or openin g, as shown. Into the eyes or openings of the links 15 are removablyinserted the hooks 17, the tubular or sleeve-like Shanks 1S of which embrace the outer singletrees 19 each .midway of the length thereof.

` The inner end of each equalizing-lever 10 carries a link 20, preferably pivotallyconnected to said lever, and these two links are connected by a short chain 21. This chain also passes over the front of a pulley or roller 22, which is journaled between the rearwardly-extending arms of a clip 23, which embraces the central singletree 24 midway of the length of the same. It will be seen that by the use of the chain 21 great freedom of movement is permitted to the middle singletree 24, so that when the draft animals are being turned or guided out of a straight line of travel no severe twisting strains 'will be brought upon the equalizing devices.

To leach end of each of the singletrees 1 9 and 24 is connected an adjustable clip 25, which is tubular or sleeve-like in form to embrace the end of the singletree, and which is formed with two rearwardly-extending arms or prof jections 26, through which passes a bolt 27, said belt serving to draw the arms closely together, and thusbind theclip securely upon the endot` the singletree. Theinner surface of the upper and lower parts of the clip 25 is formed with the two oppositely-disposed inwardly-extending teeth orpointed projections 28,Which, when the clip is tightened upon the singletree, as above described, bite into the singletree, and thus further insure a Strongconnection of the clip with said singletree. Thetugs or traces 29 are connected at their rear ends to the hooks 30, the Shanks 31 of which are of circular form and embrace the clips 25, said shanks also passing through the arms 26. It will be seen from this description that the clips 25 are so constructed as to be readily applied to and removed from the singletree, and that by loosening the nuts or bolts 27 the clips can be opened and set fartherinward or outward upon the singletrees, as desired.

lVhen it is desired to use the doubletree 1 with two instead of three animals, the bolts 7 are removed, so as to permit the equalizinglevers l() to be detached from the doubletree, and said levers andthe singletree 24,with its connections, are separated from the doubletree. The singletrees 19 are now detached from the outer ends of the equalizing-levers 10, and the hooks17 of said singletrees are inserted into the eyes or openings 6 of the projections 5 oi' clips 4; Thus the device can be easily and quickly transformed from a threehorse evener or tripletree to an ordinary doubletree without necessitating any material change of the structural parts. When used as a draft-equalizer, the power exerted by the middle draft-animal is, owing to the pivotal position of the levers 10, exactly equal to that exerted by each of the outside animals, and consequently each of said'animals is required to perform only his proportionalamount of the labor.

The device as a whole is simple, strong, and very durable in construction, and tor this reason can be produced at comparatively little expense. 4

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-

1. An improved draft-equalizer, comprising a doubletree provided at each end with a tubular or sleeve-like clip formed on its upper side with a hollow boss orprojection, also with a lug located in front of said boss, an equalizing-lever pivoted upon said boss, and a pin or bolt passing through said boss and lever and also through said clip, substantially as set forth.

2. An improved draft-equalizer, comprising a singletree having on each end a tubular or sleeve-like clip provided with parallel arms or extensions and on its inner face with inwardly-extendin g projections, and a bolt passing through said arms, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES G. STOVE.
